" c This invention relates to lighting fixtures and more particularly to those having brack-" et arms which project from the body of the fixture.'- the nvention isto provide gage'the arms with the'body' in a-novel manner which will hold them rigid with respect to the body and prevent them from "working "loose.

a Fig. 3 is an enlargeddetail sectional view showing theineans whereby the arm is rigid ly s'ecure'd'in the body ofthe fixture; and

Fig. 4 is a sectional view ontheline 4+4 of Fig. 3. Referring to the drawingsfthe body of the fixture comprises two parts, the bottom part 5 and the top part 6 which are rigidly' v secured together. by the tie rod -7. "In this adaptation of the invention four arms 8are carried by the body, but a description of one arm and the manner, in which it is so "cured to the body will be sufficient since all 7 the other arms'ar-e secured in the same way." Referringto Figs. '3 and l, the arm 8,projects through an opening 9 in thebottompart 5 of the body and extends into a socket '10 in the top part 6 of the body. This socket is pressed into the sheet metal forming the top of the body and is of a; size and shape adapted to receive snugly the upper end of the arm.v That part of the arm wit in the body is an exteriorly screw-thread 11 to receive a nut,12. A collar 13 rigidly secured on the arm is arranged to engage the outer face of the body and the nut 12 is I screwed down on the arm to clamp the bottom part of the body between itself and the collar. The parts are constructed and pro- I portioned so that when the collar. engages thebottom part of the body the upper end of the arm will be seated snugly in the socket 'andwhen the nut is screwed down on the arm against the bottom part of the body the-parts will be held rigidly in this position. To prevent the arm from being twisted when secured to the body I provide the eollar'with a flange 14 of irregular shape Y I 3111 aware that changes COIlStlllCtlOIl: and arrangement of parts may to fit within a depression of similarshap in the bottom part of thewbodyfi In the drawings the flange and the depressionare generally circular with flattened". sides 16 and "these sides are ofsufiicient length so that when the collar is seated iii the de 1 a slot IS-formed in the wallof the upper end of the arm so that the parts can be easily assembled. "It will be readily under stood that the arms can be engaged With-the bottom part of the body'and the fiange'of the collar seated'jin the depression and the nut 12 tightened against the bottom part I of the body and the wiresarranged in the slot ls'after which thef'tw parts pofwvthe y s bl and secured togetherflby I any suitable'means.

My invention provides a simple means for rigidly anchoring "the arm to the body of a lighting fixture so thatfit will be held in fixed position, against lateral or r otative movement, The invention comprises, few parts which ,are feasil y assembled gwithout arated if:occasion/requ res be made without departing from the spirit. or sacrificing the advantagesof the invention and I reserve the right to make all such changes as fairly. fall within the scope of the following claims Iclaim: 1
